运用回归分析方法并借助于计算机建立了PX－I型、PY－I型、FD型和仿LUWA型四种新型空调用离心式喷嘴的喷水压力、流量与出口孔径之间以及水滴粒径、流量与出水口孔径之间的定量关系；提供了四种喷嘴的性能曲线；对四种喷嘴在同一工况下的流量、雾化角、分散度、水滴粒径进行了对比分析。 Using the regression analysis method and the computer, four new centrifugal nozzles for air conditioning, PX-I type, PY-I type, FD type and Imitation LUWA type, were set up to measure the water pressure and the difference between the flow rate and the exit aperture, The relationship between the flow rate and the diameter of the water outlet is provided, the performance curves of the four nozzles are provided, and the flow rate, atomization angle, dispersion degree and water droplet size of the four nozzles under the same working condition are compared and analyzed.
